Struts2+Spring+Hibernate页面访问异常

[再见萤火虫]

我是用一个add.jsp来添加信息，然后跳转到list.jsp显示。

现在add.jsp页面可以正常显示，但是点击submit后就出现错误信息：
HTTP Status 404 - /jwc/stu/list.action

--------------------------------------------------------------------------------

type Status report

message /jwc/stu/list.action

description The requested resource (/jwc/stu/list.action) is not available.


--------------------------------------------------------------------------------

Apache Tomcat/6.0.29

为什么list.action找不到呢？我的struts.xml如下：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.1//EN"
"http://jakarta.apache.org/struts/dtds/struts-config_2_1.dtd">

<struts>
<constant name="struts.objectFactory" value="spring" />
<!-- /jwc/stu/add.action -->
<package name="jwc_student" extends="struts-default" namespace="/stu">

<action name="add" class="addBean" method="add">
<result>list.action</result>
</action>
<action name="list" class="listBean" method="list">
<result>/stu/list.jsp</result>
</action>
<action name="delete" class="deleteBean" method="delete">
<result>list.action</result>
</action>

</package>
</struts>

web.xml如下：

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"

查了两天了都没有解决，刚接触这个好多东西都不太了解，望指点。。。

struts2在重定向到另一个action时,需要设置type="redirect",如你的:
<action name="add" class="addBean" method="add">
<result>list.action</result>
</action>
应该设置为:
<action name="add" class="addBean" method="add">
<result type="redirect">list.action</result>
</action>

试一下

<result type="chain">list</result> or <result type="chain">list.action</result>

改了之后还是报错：

查询数据库信息是写进去了，但是list就是出不来。。。

[Jlins]

com.bit.jwc.action.StudentAction.list()

jar冲突吗？

[UPC_思念]

java.lang.NoSuchMethodException: com.bit.jwc.action.StudentAction.list()
找不到这个action的方法
有可能是tomcat发布了两个s2sh项目，将其余的项目给删掉

[JustDoIt_NotLast]

java.lang.NoSuchMethodException
包无法读取到，重新生成还是这样吗？

[再见萤火虫]

我就一个项目额。。。jar冲突？具体是什么呢？

add是可以写进数据库的，就是list让他显示的时候就出问题了。。。这两个应该是平行的啊，怎么会一个可以一个有问题呢。。。

[再见萤火虫]

OK,终于解决了，确实有个jar包冲突了，还有个大小写的问题。。。初学好多东西搞不明白额

谢谢各位了~~
